Lua Npcsystem - where is problem?

[Komigz]

Hi i have problem with my npc system. I'm using mystic spirit 0.2.15
Namely when i have 2 lines with text, like this

npcHandler:say("Zzo you are offering your help to a lizzard? Hmm, unuzzual. I don't know if I can fully truzzt you yet. ...", cid)
npcHandler:say("You'll have to work to earn my truzzt. Are you zzure you want to offer me your help?", cid)

then npc say first second msg and later say first msg, it like that

17:31 Zalamon: You'll have to work to earn my truzzt. Are you zzure you want to offer me your help?
17:31 Zalamon: Zzo you are offering your help to a lizzard? Hmm, unuzzual. I don't know if I can fully truzzt you yet. ...

anyone know how to fix it ?
and how add delay between first msg and second?
like that

first message
wait 2 seconds
second message
